how much NOS are you planning to run? You basically have to tune your NOS to the controller vs the typical vice versa of that.

i'm planning about 50 shot.at this moment i only have a TFI box to add extra fuel,but this still makes it difficult.

from what i have heard of others experiences, i think a 50 shot might be too small with the amount of fuel a fast fi box adds. Not to turn this into another ecu flashing thread, but you might want to at least read over this material, makes a dry shot pretty easy

thats true makes a dry shot pretty easy and cheaper,but i own a busa 1999.what can i used

 

[smithabusa]

power commander, hub, with map switch I would think

My question is If i add with the TFI approx 17% extra fuel for a 38 jet dry shot, when not spraying will i foul the sparkplugs.

Thats pretty rich, id figure out a better way imo

Is it to rich for a 38 jet or to rich that it would foul the sparkplugs how much percentage should be applied for a 38 jet
